Details continue to emerge after last weekends UFC 183. Silva Diaz delivered exactly as expected. The fight was instantly dubbed one of the best in history. Yet it's the pre fight drug tests that today are mustering up all the murmurs.

Apparently Nick Diaz failed a pre fight test. He came up positive for marijuana. In the meantime the UFC has released word that former champ Anderson Silva tested positive for steroids. It was an exciting fight with Anderson Silva earning the unanimous decision victory, but now it may go down in the record books as a no contest — like it never even happened. All of this thanks to two failed drug tests.
